(Refer to FAA-CT-8080-5H, Figure 30.) Using a maximum demonstrated crosswind component equal to 0.2 VSO, what is a pilot able to determine? VSO: 60 kts Landing Rwy: 12 Wind: 150° at 20 kts

FAA Figure 30Wind component chartFAA-CT-8080-5H · Flight & Ground Instructor supplement
How to read it: Follow the arc for the wind speed to the radial for the angle between wind and runway; read headwind on the left and crosswind on the bottom.
A

Headwind component exceeds recommended limits.

B

Crosswind component is within safe limits.✓ Correct Answer

C

Maximum demonstrated crosswind component is exceeded.

Explanation

Runway 12 is 120 degrees and the wind is from 150, a 30-degree angle, so the crosswind component is 20 x sin 30 = 10 knots (the chart gives the same). The maximum demonstrated crosswind is 0.2 x 60 = 12 knots, so the crosswind is within limits; the headwind component (about 17 knots) is not a limit.
